Specification of Letters Patent.

Application ledDecember 19, 1910, Serial No. 598,072. Renewed January 25, 1913. Serial No. 744,243.

To all whom t may concern:

Be it known that I, CHARLES D. SEF.- BERGER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Conveyers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention provides an endless conveyer or carrier comprising a Vseries of connected and moving sections to transport passengers or freight from one door or level to another which assume a step-like character or formation on the inclined portion of the carrying run between the floors and provide entrance and exit platforms of vunbroken continuity curved with reference to a horizontal plane at the landings of the different floors or levels,

The main object of this invention is to provide or afford greater ease of access to and exit from a moving carrier at the tloors or levels connected by a carrying run thereof, especially in the case of freight which may then be easily pushed upon or from the moving carrier.

-The invention consists in the arrangements and or anizations of parts hereinafter particularly escribed and then stated in the appended claims.

In the accompanying drawings which illustrate an` embodiment of the several features of thepresent invention: Figure 1 is a side view, diagrammatic in characterhof a traveling carrier or oonveyer illustrating an application of my present invention; Fig. 2 is a similar view upon an enlarged scale of certain parts shown in Fig. 1, illus- 40 trating more articularly the platform at the u per lan ing; Fig. 3 is a plan view of lthep atform-section of Fig. 2; Flg. 4 is a view similar to Fig. 1 upon an enlarged scale illustrating more particularly the plat- 45 form at the lower landing, and Fig. 5 is a plan view of the platform-sections of Fig. 4. Referring to the drawings the numeral -indicates a series of sections, preferably in the form of steps each consisting of a iser supported'upona suitable frame provided with a wheel l1 or some equivalent support such for example asa sliding shoe or runner, mounted on the ends thereof and traveling -on suitable tracks together by rack-links 13 to which power is applied by means of a suitable drive wheel or sprocket 14 for imparting motion to the sections.

The conveyer or carrier is adapted to travel upon upper and lower ways, each provided with tracks for the step-supporting wheels extending on inclincs between the dilicrcnt levels or oors 15 and -16 and upon suitable curves adjacent the floors, the tracks being so iarranged with relation to the carrying wheels that the step' or-sections are'in step-like formation on the incline and with their tread-surfaces in a continuous curve at each landing. In the form shown the carrier is adapted to transport between an upper and a lower landing, and it is of course understood that when it is adapted to transport between more than 4two levels or landings the tracks will be correspondingly extended. At the upper level the tracks of the carrying run extend in a curve whose highest point is at tlie'front end of the upper plat-forni formed by the treads and approximately under the associated landing 15, and at the lower level the tracks for the carrying run extend in a curve whose lowest point is at the rear end of the lower platform formed by the treads and approximately under the associated landing 16. 'The curved tracks for the upper landing merge into the inclined tracks, and the latter merge into the curved tracks for the lower landing so as to form a continuous upper way between the landings, and the tracks preferably also are curved at the ends and continue around and along the lower way to afford a continuous circuit. The present illustration shows the arrangement for a downwardly traveling carrier and which would be reversed for an upwardly traveling carrier.

The links 13 connecting the axles of the steps or sections are divided and each is in` the form of a toggle. The joint of each link isprovided with a depending arm 17 having an offset 18 at its free end engaging a guide 19 around the-circuit, these arms controlling the relation of the sections or steps.' The distance between the axles of adjacent steps is of course greatest on the straight-awayrun on the incline and decreases when the steps are on a curve, and hence the links are made fiexible so that they-may hreak-down atLthe curves and thus automatically lengthen or shorten under various requirements of operation on the runs. The guide 19 at the landings is spaced farther away from the tracks than it is on the inclined carrying portion of the.

run, so that vthe arms 17 are drawn down as the sections pass over the `landing-tracks to break-down the links so that the nosings of the steps or sections may abut without gaps, and when the sections pass to the inclined portion of the runthe links' may straighten out to accommodate the increased separation between the step-axles.

F rom the foregoing disclosure it will be seen that'the in1tial tread. at the top and the last tread at the bottom are practically in line with the Hoor platesl and 16 respectively, and that all the tread surfaces comprising either the entrance or the exitplatform as at Figs'. 3 and 5, respectively, are in a continuous curve, the contiguous nosings of adjacent: steps'or sections being` there together without gaps on the same line and are vnot steppedup with reference to each other as would be the case if the existing type vof elevator or carrier composed of similar sections traversed tracks curved at the landings. The platform at the entrance curves away from the landing l5, and at the exit curves toward .the landingv 16, so that greater ease of access andv exit. is afforded and freight may .easily be pushed on or oi thecarrying run.
